Summer Festival was a CBC summer weekday series. Each day guests and viewers shared in the excitement of being on-the-spot at some of Canada's most famous festivals. A different host performed duties in each region. In addition to events from such locations as Klondike Days in Edmonton or the Lobster Festival in P.E.I., the show included B.C. astrologer Geoff Gray-Cobb, with horoscope predictions every Monday.
